UNITED STATES PATENT OFFICE.

ALFRED B. FOWLER, GEORGE E. WARREN, AND WARREN C. EVANS, OF EXETER, NEW HAMPSHIRE, ASSIGNORS TO THE ROOKINGHAM MACHINE COMPANY, OF SAME PLACE.

HEEL-BURNISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 488,997, dated October 21, 1890,

Application filed November 25, 1887. Serial No. 256,056. (No model.) l

To a/ZZ whom it may concern:

Be it known that we, ALFRED B. FowLER, GEORGE E. WARREN, and WARREN C. EVANS,

' all citizens of the United States, and all residents of Exeter, in the county of Rockingham and State of New Hampshire, have jointly invented new and useful Improvements in Heel-Burnishing Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in heel-burnishing machines, and it is carried out as follows, reference being had to the accompanying drawings, wherein- Figure l represents aside elevation of the improved machine. Fig. 2 represents a rear View of the same. Fig. 3 represents a vertical section on the line A B in Fig. 1, showing the revolving jack; and Fig. 4 represents a horizontal section on the line C D, shown in Fig. 1. Fig. 5 is a detail plan view of the jack-centering device.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings. ,A

This invention relates particularly to an improved rotary jack 'and means for locking the same in position while burnishing and brushing the heel; also, in an improved de- 4vice and mechanism for automatically brushing the heel after it has been burnished.

The other parts of the machine are substantially like those shown and described in the patent granted February 14, 1888, No. 37 7,826, to A. B. Fowler for improvements in heel-burnishing machines.

a is the standard of the machine, with its bearing a for the rock-shaft d, and b is the rear post having upper bearing b for said rock-shaft d, as shown and described in the above-mentioned patent.

c is the rotary driving-shaft with its fast and loose pulleys c and c, as usual.

The mechanism for imparting a rocking motion to the shaft d from the rotary shaft c is the same as shown and described in the former patent above mentioned.

h is the burnishing-tool secured to the forward end of the burnisher-shaft h, which latter is universally jointed at f3 to the rotary longitudinally movable and oscillating shaft ff', and such combined motions are imparted to said shaft f f from the rotary drivingshaft c by intermediate connecting mechanism, as shown and described in the aforesaid patent.

h is the radially-yielding forward bearing for the burnisher-shaft h, such bearing having the forwardly-projecting lip h4, in a manner and for the purpose as set forth in the aforesaid patent.

D D are the springs for pressing the burnisher-tool against the heel while in the act of being burnished.

T is the treadle pivoted at t and having connected to its inner end the link T', the upper end of which is connected to the plunger T", that is guided in the bracket co, secured to the standard a, said plunger T having secured to its upper end the lifter-cam T3, that is brought against the projection h4 when the treadle T is depressed in the same manner as shown and described in the aforesaid patent. The treadle T is normally held in the position shown in Fig. 1 by the iniiuence of the spring U when the machine is in operation, and the machine is stopped when the treadle is depressed in a manner and by mechanism as fully described in the above-V mentioned patent.

We desire to state that the parts of the machine as above described form no part of our present application, and are only brieily mentioned for the purpose of more fully showing the nature, construction, and operation of our present improvements.

The improved rotary jack is constructed as follows: To the front of the standard a is firmly secured the cylindrical shaft or spindle R, the outer end of which is supported andA held in place by means of the post or rod R', secured in its lower end to the door and hav'- ing, preferably, a cap or head -R in its upper end, to which the outer end of the spindle R is suitably secured.

S is the revolving-jack frame, and Sis its hollow hub, that is journaled on the horizontal spindle R, as shown in Figs. 1, 3, and 4, and

adapted toslideforward and back on the latter, so as to bring the shoe-heels held by the jack in positionwhen being burnished and brushed and to withdraw said heels and the jack after the work is done, so as to enable the jack to be turned around its axis one-fourth of a revolution, as will hereinafter be more fully described. The frame S has in its outer ends the four horizontal bearing-sleeves S S S S', in each of which is adjustable the clampingsleeve S and the plate S3, secured to the end of such sleeve S The sleeve S is adjustable Within the sleeve S by means of the screw S3 and hand-wheel Sin the same manner as shown and described in the patent aforesaid. The screw-shaft S3 `works in a screw-threaded portion in the sleeve S, the latter being free to move forward and back in the sleeve Sjwithout turning around its axisfn S'L is a bearing for the screw-shaft S3, said bearing being secured to the outer eind'of the sleeve S betweenI the hand-wheel S3 and a collar on `thescrew-shaft S3, as shown `and described in the aforesaid patent, by Whichthe screwshaft S3 may be rotated' without moving longitudinally. S7 S7 areftheilheel-top-lift rests secured to or cast in one piece with the frame S and having heel-plates S3 secured to them, as `shown in Figs; l, 3, and 4.- 1 f In the innervend of the hollow hub s there are longitudinal grooves' s s s" s', equal in number to the j ack-screws S3, and to the shaft R is secured a projectionr, (shown in Fig;"3,) that is made to enter one of the grooves IS when the "jack-frame' S is pushed frwardin workingV position, thus holding or locking the jack-framein its proper position'rand preventing it-from turning around its axis While the Work of burnishing and brushing theheel is being done.

For the purpose of aiding in centering the jack-frame S when it is pushed forward in working position we make `on Ythe inner end of each'of the top-lift :rests Sla V-shaped proj ection S3, adapted to enter a correspondingly shaped taperingrecess 0,3 in the front'of-the stationar bracket a, as `shown 4in' Fig. 5.

After the rotary `jack S has been turned around its axis a fourth of a revolution and moved longitudinally into operative position it is automatically llocked in Vsuch position by the spring-pressed pawl a4, pivoted `at a5 on the bracket a, and having its forward end adapted to'enter a locking notch or recess S13 on the 4under side of that one of the heel-toplift rests S7 that is yfor the time being opposite to the-bracket a, as shown in Figs.- l and 3.

After the heel is burnished or brushed,'or bot-h, thelocking-pawl a4 is disengagdfrom the top-lift lrest by "the depression of the treadle T by the `action of a projection T4 on the side of the rod or plunger T, as shown in Fig. 1, that cornes in Contact with the rear end ofthe pawl a4 and trips it suiciently to cause it to be disengaged from the notch in the top-lift rest S7, after which the operator pulls the jack-frame S toward him far enough to cause the locking projection fr on the post R to be disengaged from the guide-groove S in the hub S, after which the said jack-frame S may be freely turned a quarter of a revolu- `tion around it-s axis and again pushed into a corresponding operative position, there to be again locked While another shoe-heel is being burnished and brushed, and so on.

rlhe automatic mechanism for brushing the shoe-heels after they have been burnishedthat is, to brush'one burnished heel while an other one is being burnished, and so on in rotation--is constructed as follows: In stationary bearings b, a, and a7 is located the rockshat't E, which is automatically rocked in its bearing by means of the links E', connected in its ends to levers 'E'.JandD secured, respectively, to thesh'afts Eand cl, as shown in Figs. l and 2." To the rock-shaft" E are se# which serve as bearing for the'shaft E3, which is given a quick rotary'motion' by means of a pulley C', securedtothe driving-shaft ,'and a belt C, leading from" it to thepulley E,

^ that is loosely journaled on the rock-shaft E,

and a belt E7, leadi'ngfrom` the latter pulley to the pulley E3, secured `to the shaft E5, as shown in Figs. l and 4;" The shaft Eisilniversally jointed at `X to the' brushfshaft G, which latter has securedr toits freeend the cylindrical brush G'. (Shown in Figs. 1, 2, and 4.) To the rock-shaft Eis secured the forked arm or lever G in iwhich isguided the bear# ing G3 for 'the brush-s`haft G,'as shownin Fig. 4, said bearing beingfree toadjust itself out andin on the lforked arm or lever G according to the curvature of the'heelof the' boot or shoe on which the rotary brush'Gi is acting. j For the purpose ofpermitting the rotary brush G to be held against'the` boot or shoe heel with a proper pressure and to" yield to inequalities in the curvature of such heel we journal the brush-shaft G near thebrush G ina sleeve" or bearing G4, that is pivoted in the outer'end of the forked `piece orhanger G5, the shank or spindle G3 of which passes through anarm or lever G7,"`secured to the rockshaft E, and has surrounding" it acoiled spring G3, between the lever Gland a collar G9, secured `to the spindle G6,"as 'shown in Fig. 4.

'E3 in Figs: l, 2, a1d4 is ay balance ordonnterweight secured to the rock-shaft'Eforthe purpose of lbalancing "the shaftsA E5 ."G" and theirfrespective -bearirigs, pulley, and brush, so as to keepthe said shaft Eproperly balanced during itsrocking motion 1 By means of the rockshaft"d,its lever D3, the link E", and lever E on the shaft 1E a rocking motionis i'np'arted tothe-'lattenj'causing the brushG` to `swing from'breastto breastl of the "shoe-heeI-` that isheld 'in' lthe jack, and during'fsuch swinging movement of the brush `it is' given a quick rotary motion around its axis by means of thel connecting mechanism from the driving-shaft c to the lcured the levers E3 and E4, the outer'ends of IOO IIO

IIS

shaft E5, as above described. During such motion of the brush G it is held against the heel with the proper and desired pressure by means of the spring G8 on the spindle G6, as hereinbefore fully described. Thus it will be seen that while one shoe-heel is being automatically burnished another one previously burnished is being automatically brushed, and thus the heels are automatically burnished and brushed in one and the same machine without any other manipulation than securing the boot or shoe to the jack, turning the latter a part of a revolution around its axis, and removing the shoes from the jack after being burnished and brushed, thus saving a great deal of time and labor in the art of finishing the heels.

Having thus fully set forth the nature, construction, and operation of our invention, we wish to secure by Letters Patent and claiml. In a burnishing-machine, the improved jack, as described, consisting of the horizontal shaft R and the hub s, journaled on the latter and adapted to slide forward and back on said shaft to turn around it and to be locked in position, as described, in combination with a series of toplift supports S7 and longitudinally-adjustable clamping-plates S6, actuated by clamping devices on the jackframe S, as and for the purpose set forth.

2. In a burnishing-machine, the automatic heel-brushing device, as described, consisting of the rock-shaft E and the rotary brush G on the shaft G, mounted in bearings on said rock-shaft and universally jointed to the rotary shaft E5, locatedin bearings E3 E4 on said rock-shaft E and'adapted to yield against the action of the spring Gs as the said brush-shaft is rotated and oscillated, as and for the purpose set forth.

3. In a burnishing-1nachine, the combination of the following elements, namely: a plurality of rotary and longitudinally-movable jacks having devices for clamping the shoes in position, a burnishing-tool, a rotary oscillating and yielding brush, and means for locking the jacks in position.

4. In a burnishing-machine, the supportingshaft R and the rotary and longitudinallymovable jack-frame S s, mounted thereon, in 5o combination with the treadle T, the rod T, and spring-pressed pawl a4 for securing the jack in working position, substantially as described.

5. In a burnishing-machine, the rock-shaft E, having'secured to it the bearings E3 E4, and having rotary shaft E5 j ournaled in said bearings, the balance-weight E, secured to the rock-shaft E, and the brush-shaft G, universally jointed to the shaft E5 and having brush G secured to its free end, and having such end journaled in the radially-yielding bearing G4, substantially as and for the purpose set forth.

6. The combination of a series of rotary and longitudinally-movable jacks having de-v vices for clamping shoes in position, a fixed shaft on which the same are movable,alock ing mechanism to prevent longitudinal and rotary movement of the jacks, a number of rotating tools to act on the shoes held by the jacks, and lifting mechanism to move the rotating tools away from said boots or shoes to permit the jacks to be moved out of the path of movement of said tools, substantially as shown and described.

7. The combination 'of a rotary and longitudinally-movable jack'frame having anumber of clamping devices for securing shoes in position, a fixed shaft on which the jack-frame is mounted, a number of oscillating Vrotary and yielding tools, and locking mechanism for holding the jack-frame in position during the operation of the tools, substantially as shown and described.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, on this 5th day of October, A. D. 1887.
